Specification of Letters Patent.

Patented Aug. 2st, 1909.

Application filed January 2, 1909. Serial No. 470,290.

To all whom it may concern:

lie it known that I, MEYER S'rnnilnzin', a subject of the Emperor ofRussia, residing at Newark, in the county of Essex and State of llcwJersey, have invented certain new and useful Improvements in Cocks; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying ("lrawings, and to characters of reference markedthereon, which form a part of this specification.

This invention relates, generally, to improvements in safety-attachmentsfor locking or holding the valve-spindles of cocks of the various kindsin their closed positions against being turned accidentally; and, theinvention relates, more particularly, to a novel means or retainingdevice which is especially adapted for use with the turning orfinger-piece of the valvespindle of a gascock, or other cock, and is ofsuch a construction, so that while the plug or valvespindle of thegas-cock can be turned on and otl in the usual manner, the plug or valvespindle is locked or held against accidental turning in its normalclosing position.

The invention has for its principal object to provide a neatand cheaplyconstructed looking or retaining means adapted to be used with the usualoscillating plug or valve stem and its turning member or lingerpiece ofa cock, whether for gas, liquids,-or otherwise, which operates in such amanner that the movable parts are locked or held in their normal initialpositions against accidental turning, but the retail'iing or holdingmeans being readily manipulated by the person, almost simultaneouslywith the turning of the linger-piece for the purpose of providing adirect passage for a gas or liquid through the valveplug or spindle andthe interior of the cock.

Other objects of this invention not at this time more particularlyenumerated will be clearly understood from the following detaileddescription of my present invention.

With the various objects of my present invention in view, the inventionconsists, pri marily, in the safety-cock hereinafter more particularlyset forth; and, the invention consists furthermore in the variousarrangements and combinations of devices and parts, as well as in thedetails of the construction of the same, all of which will be more fullydescribed in the following specification and then finally embodied inthe clauses of the claim which are appended to and which form anessential part of this specification.

The invention is clearly illustrated in the accompanying drawings, inwhich Figure 1 is a side elevation of a gas-cock provided with avalve-spindle or plug and a turning member or fingerpiece foroscillating the spindle, the fingerpiece being pivotally connected withthe spindle and being provided with a looking or retaining means forholding the parts in their normally locked relation; Fig. 2 is a similarview of the said parts, the valve-spindle and its pivoted fingerpiece,however, being shown turned in a plane at right angles to the plane ofthe fingerpiece shown in said Fig. 1; and Fig. 3 is a bottom view of thecock and parts. Fig. 4 is an end view of the cock, looking in thedirection of the arrow 05 in said Fig. 1; and Fig. 5 is a similar viewof the same, looking in the direction of the arrow g in Fig. 2. Fig. 6is a horizontal sectional rep resentation of the device, said sectionbeing taken on line (56 in said Fig. 1, looking in the direction of thearrow 2. Fig. 7 is a transverse vertical section, said section beingtaken 011 line 7-7 in said Fig. 1, and said view being made on anenlarged scale; and Fig. 8 is a similar view with the valve-stem or plugshown turned at right angles to its former position indicated in saidFig. 7 Fig. 9 is a side elevation of a gas-cock of a slightly modifiedconstruction, provided with a valve-spindle and a pivoted handleconnected therewith, said handle being pro vided with a holding orretaining means embodying the principles of the present invention; andFig. 10 is a similar view of the gascock showing the handle turned atright angles to its normal position indicated in said Fig. 9.

Similar characters of reference are employed in the above describedviews, to inclicate corresponding parts.

In the accompanying drawings I have shown the principles of my presentinvention as applied to a gas-cock, but it will be understood that itmay be applied to any other form of cock, faucet, or the like.

The gas-cock in this instance consists of a main body formed with acentrally disposed hollow member 1, in which is rotatablydisposed atapered valve-spindle or plug 2 formed with a laterally extending duct-3 which may be located at right angles to or may be moved in alinementwith the tubular interior of the inlet member a and the outlet member 5connected with and extending respective from the opposite sides of thesaid hollow member 1. The oscillating valvespindle or plug 2 isrotatably secured within the chambered part of the member 1, being heldin place at its upper end-portion, by means of the usual washer 6 andscrew 7, while its lower and large end-portion 8 extends from an openingin the under or lower side of said member 1, substantially as shown. Thelower marginal edge-portion of the said body or member 1, whichsurrounds the said lower opening, is made with a receiving depression orrecess 9, formed by the part 10 and a projection or lug 11, and with thecut-away part 12 and a stop 13. In its opposite part, the said marginaledge-portion is made with a cut-away part 1 1 forming with saidedge-portion suitable stops 15 and 16. Connected with and preferablyforming an integral part of the said lower and large end-portion 8 ofthe valve-spindle or plug 2 is an annular rib or projection 17 whichforms a disk-like member or element, and extending from the lower faceof the same are a pair of perforated ears or lugs 18 provided with apintle or pivot-pin 19 suitably secured to said ears or lugs andextending directly across the space formed between the said ears orlugs. Movably arranged in said space and pivoted upon said pin 19 is theupper portion 21 of a suitable turning member or fingerpiece, as 20, thelatter being made with a recessed part 22, which is preferably providedwith a pin or post 23. Extending from the upper edge of the said portion21 is a lug or projection 24, which extends into and is movably fittedin an opening or slot in the annular rib or projection 17, as clearlyillustrated in the several figures of the drawings. The upper portion ofsaid lug or projection 24 extends slightly above the upper surface ofsaid annular rib or projection 17 and is provided with a vertical pin orpost 26, said post or pin 26 iuider normal conditions being arranged inthereceiving depression or recess 9, substantially as shown in Figs. 1and 6 of the drawings. The means for normally forcing this post or pin26 into said recess 9 is a suitably coiled spring 27 which has its oneend-portion arranged over the pre viously mentioned pin or post 23 inthe recessed part 22, the said spring being suitably compressed andhaving its other end-portion arranged over the lower end-portion 29 of asuitable pin or post 28, said pin or post being secured to said annularrib or projection 17, directly opposite the said lug or projection 2 1,and having said end-portion 29 projecting from the lower or undersurface of the rib or projection 17, substantially as shown. Thecompressed coils of this spring, as will be clearly evident, cause theturning member or fingerpiece 20 normally to stand in the positionsindicated more particularly in Figs. 2, at and 7 of the drawings. Theupper end-portion of the said pin or post 28 extends into and is movablyarranged in the cutaway part 1 1, so that it can be moved against eitherstop 15 or 16, as and for the purposes to be presently more fullydescribed.

Having in the above description in a general way set forth onearrangement and combination of devices and parts showing one embodimentof my present invention, I will now describe the manner of releasing theturning member or fingerpiece from its normally locked relation, foroperating the valve-plug or spindle and to provide an open or directpassage for the gas or liquid through the cock.

By taking hold of the edge-portion 80 of the turning-member orfinger-piece 20, and pulling in a downward direction, in the directionof the arrow 0 in Fig. 41- of the draw ings, a sufficient movement ofthe said fingerpiece 20 is produced so as to withdraw the post or pin 26from its normally locked or holding engagement from within the receivingdepression or recess 9. The fingerpiece, at the same time, can be turnedin the usual manner, the pin or post 28 moving in the cut-away part lluntil it is brought against the stop 15, whereby the movement of thefinger-piece and the valve-spindle or plug is arrested so as to bringthe parts of the cock into their opened relation, shown in Figs. 2, 5and 8 of the drawings. At the same time, having released the pullingforce from said portion 30 of the fingerpiece 20, the spring 27, thecoils of which have been still further compressed, will cause thefingerpiece to assume its former position with the said post or pin 26extending into the cut-away part 12 and arranged directly against theside of the stop 13. As shown more particularly in Fig. 6 of thedrawings, the side of the projection or lug 11 is chamfered, so that,when the lingerpiece 20 is moved in its opposite direction for thepurpose of closing the valve-spindle or plug, the pin or post 26 willreadily move over the said chainfered surface of the projection or lug11 and will again be forced into the said recess 9, be-

tween the stops 10 and 11, to once more hold or retain the turningmember or fingerpiece 20 in its locked position against accidentalturning, as will be clearly evident.

In I*igs. 9 and 10, I have shown a slightly modified construction ofgas-cock, the same, however, still embodying the principles of thepresent invention. Referring now to the said figures of the drawings,the main bodyportion 31 of the cock is made with a receiving recess ordepression 32 formed by the part 33 and a short lug 34, the said bodybeing also cut away, as at 35, so as to provide a suitable stop. Theportion 37 of the valve-spindle or plug 36 is provided with a laterallyextending projection, as 38, and with a small pin or lug 39, the latterbeing movably disposed in the cut-away part 35 and the recess 32, beingadapted to pass directly beneath the lower end of the lug 34 during theoscillatory movements of the valve-stem or plug 36, as will be clearlyevident. The said stem or plug 36 is also provided upon its lower endwith a pair of perforated ears or lugs, as etO, provided with a pintleor pivot-pin ll suitably secured to said ears or lugs and extendingdirectly across the space formed between said ears or lugs. Movablyarranged in said space and pivoted upon said pin a1 is a valve-spindleturning member in the form of a lever or arm 42 which is provided at oneend with a handle or fingerpiece 43 and has a projecting end-portion 4%arranged directly beneath the laterally extending projection 38. Aspring, as 45, is arranged between said projection 38 and theend-portion 44:, substantially as shown, the purpose of this springbeing to force the free end of a post 46 under normal conditions intoholding or retaining engagement with the receiving recess or depression32, so as to prevent any accidental turning of the valve-stem or plug,as will be clearly evident. By pulling the arm or lever l2 downwardlythe free endportion of the post d6 is withdrawn from the receivingdepression or recess 32, whereby the valve-spindle or plug can be turnedby means of the said handle or lever, the spring 45 cooperating with thelever to return it to its horizontal position, so that the free end ofthe post 46 will extend into the cut away part 35, the small pin or lug39 limiting the rotary movement of the valvespindle by coming in contactwith the shoulder at the end of the said cut-away part 35. It will beevident that the operation of the several parts shown in said Figs. 9and 10 is the same as that described in connection with the constructionof the device illustrated in Figs. 1 to 8 inclusive.

I am aware that some changes may be made in the arrangements andcombinations of the various devices and parts, as well as in the detailsof the construction of the said parts, withoutdeparting from the scopeof my present invention as described in the foregoing specification andas defined in the appended claims. Hence, I do not limit my presentinvention to the exact arrangements and combinations of the devices andparts as set forth in the said specification, nor do I confine myself tothe exact details of the construction of any of the said parts asillustrated in the accompanying drawings.
